This week I flew over to Berlin for the first time to buy a few records, learn how to wear a bum bag as a cross body bag, and, most importantly, to see some wonderfully curated shows. As I had time to consider these in the past few days I realised that tactility and memory were threads connecting Henrique Neves, Louise Bourgeois and Philip Wiegard  as each artist presented traces of his or her past through their chosen medium.
